ILLUMINATING APPLIANCE.

Application filed November 9, 1915.

To all whom it may concern:

Be it known that we, FREDERICK AUGUS- TUS ANDREWS and THoMAs GAsKELI. ALLEN, residing at Westminster, London, S. W., England, have invented certain new and useful Improvements in Illuminating Appliances; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention relates to the manufacture of a new article suitable for obtaining transmitted or reflected light effects, and is characterized by interposing textile materials, paper that is perforated or translucent or opaque sheet material such as thin metal, paper or cloth that is perforated to obtain silhouette effects, between protective transparent or translucent parts, such as glass, andbinding or framing said protective parts with the interposed materials to form a composite unit.

The invention is capable of a large number of applications, but finds an extensive field of utility in connection with lampv shades, window and casement lights, or where similar transmitted or reflected color efl'ects'are desired. vAt the present time the materials ordinarily employed for lamp shades and the like are exposed to the risk of fire and deterioration from dust and wear; furthermore their surfaces usually vhave in themselves very little reflective power on the light they inclose. The invention as applied to these articles consists in inclosing the said materials between protective or reflective parts of glass and the like,"arrangements being made whereby the glass parts and the material inclosed are fastened together so as to form a complete unit. Lamp shades and the like'articles may be so made of curved or hemispherical shape, and in cases where the invention is applied to flat composite units it is'necessary that the external .dimensions of the covering parts conform the one withthe other. That 7 is to say, that if the covering sheets of glass are rectangular, then the edges of the said parts are in alinement. If on the other hand the covering parts are curved hemispherical or globular, the one part is made to lie with in the other, and conform therewith in shape.

The invention will however be better un- Specification of Letters Patent. Patented J 119 19, 1917,

derstood by reference to the accompanying drawings in which Figure 1. shows the invention as applied to an ordinary electric lamp shade.

. Figs. 2, 3, l, 5 and 6. show alternative methods whereby the protective parts are interlocked.

Figs. 7 and 8. show in elevation and part section respectively a panel unit made in accordance with this invention.

Referring to the drawings, the ordinary lamp shade or like material a is inclosed between protective glass parts 6 and 0, the one part c'being made to Conform and lie within the outer part Z), the interposed material a which in such application is preferably of a textile nature, is secured over the inner glass part c the upper part being provided with a hem or stitched portion d. The material a may be secured over the glass part 0 in a stretched, plaited or puckered condition, and arranged so that its ends e protrude at the base. At this latter point a ring f attached to or forming part of the same material is formed, and provided with ed-gings g, which may be reinforced if required with a ring of wire, rubber or the like material h. The upper edging g is adapted to engage the upper surface of the rim of the outer protective part 6, while the lower edging g is adapted to engage the inside of the rim of the inner glass part c.

In operation it will be seen that by these means the parts a, b, and c are interlocked against unintentional relative displacement, the material in this case acting in conjunction with the edging g as a binding material. In Fig. 2 an alternative method is provided in which the lower rims of the parts 6 and c are caused by means of an insertion to interlock. To effect this therim of the inner protective part 0 is extended and curved upward as at c, and is provided with a notch or groove '6, a similar notch or groove 2' being formed in the lower rim of the outer protective part b. The material a secured within these two protective parts is formed with a single edging g which in this case is preferably reinforced with rubber or the like material which can be squeezed into the notches and when once in place will serve to lock the parts a and 6 against unintentional disengagement. Alternative methods of securing these are shown in Figs. 3, 4:, 5 and 6. In Fig. 3 the method of locking the v parts a and b is identical with that of'Fig.

2 except that the parts b, and c which are notched to retain the interlocking medium 9 curve downwardly as shown.

In Fig. 4 the lips or rims of the protective parts I) and 0 are left plain as in Fig. 1, and

are interlocked against disengageme t y.

means of cleats k which are passed through the edging g and then bent in a plurality of instances to grip the two parts 6 and 0 to-, gether. In Fig. 5 plain lips or rims" are again employed, but the fabric a protruding from the said parts is threaded between slots is shown a' further modificationwhereby' the inner protective part a is bent upwi th a:

single plain lip or gutter 0 to accommodate the lower rim of the outer protective'part b, the! interposed material a being provided with an external edging gwhich in this'form serves to lock the two parts from disengage ment. In lamp shadesof this formation which are adapted to be secured bymeans of the holding rings of the lamp shade I, holders, the loweredges of the fabricneed not necessarily protrude and a somewhat heightened and improved artistic effect is produced if the fabric a is left without decided termination, such as a metal band or I ringto accentuate the outline of the shade.

This may be effected in the case of an electric or ,like lampshade by securing the enter protective parts I) and a witha gripping collar (not shown) separate from or forming part of the lamp holder thussecuring the said parts inrelative fixity when the ma: terial may terminate within the confines of the shade parts and may be sealed therein in a dust free condition by inserting copal varnish or like transparent mediumv that may also be of an adhesive character into the space between the glass shade parts.

,Bymeans the foregoing it will be ob,-

served that shades for mpsmade or manufactured from materials ordinarily employed maybe protected from risk of fire, or from contact with dust, whilethe original colorsmaybe' preserved. The invention also has the advantage that artistic effects are obtainable thereby which are not obtainable inshades or the like constructed whollypf glass, porcelain or thelike. In a modified form the colors ma'y beimprov'ed upon or supplemented, as for instance, the inner shadegpart 0 may be madetransparent, the material a; be colored and the, protectiye parts b be madefrom translucent or tinted glass, so that, when light is transmitted the observer hasthe effect of the combination of the colorspossessedby a and b. In1.Fig's,,7 and 8 panels are shown, in which the prote'ctive parts I) and 0 are employed inclosing the naterial a-., These parts?) and c are made to conformthe one with the other so far as their external dimensions are concerned, andare bound or framed according to the application of the invention, with metal wood, paper or the like binding or framing material f. In this case, or in any of-the foregoing applications the effect of a leaded light may be obtained by superimposinga patch work outline a of opaque material. A composite unit of rectangular shape may be employed for window lighting or for any scheme of" decoration, or again these individual panels may be of small dimnaoaaemma the one to the other and made up intoshades, or the like devices for transmitting light. I

will understood that the glass covering parts may be bent or molded into any desired shape, and the material placed betweensamef so long as a composite unit is produced. Again these composite units may be mounted in 'a suitable frai'riework, or may be bound tcgether with wood, metal, paper or any other suitable binding material, and for economyin space for packing and portability these sections may be detachable from eaclrnthem and when assembledrnay be placed in their frameat such an angle in relation to the source of light as; to secure a maximum of reflection in any desired direction The interposed fabric may be continuous or interrupted, and the fabric where opaque, semi-opaque, transparent or transhicent, may be perforated, ora combinationoftranslucent material may be employed in conjunction with a. perforated opaque material, whereby a silhouette effect is obtained with a coloredbackground. In the event of the outer protectiveparts ofthe panel or shade being secured together bymeans other the fabric itself, the material iriterposed may be secured by means of an adhesive to one. or otherof the said parts, or alternatively the fabric in a variety of colors may be Inade in sections, and caused to adhere to one shade of glass and then covered by the other shade, the patch work opaque edge or as shown in Figs. 7 and 8 being secured to the on or the other of the parts I) a11 cl,0, so as to disguise the joins in the material a, and give a more realistic representation of stained glass. Again in the event of applications where the light is only required to be shadedinone directiOn, as is necessary for table decorations and ofiice fittings, the shademay be madein two semicylindrical pieces of glass .with the fabric placed between them. Furthermore the protective partsb and 0 may be niadein mica, talc, horn, celluloid, casein or thelike transparent or translucent material. The invention proyides themeans for considerable artistic development, for example articles of furniture such as overmantles, sideboards, and the like may be fitted with panels made according to this invention and the room lighted without the need of independent illumination fittings. The invention also makes it possible to manufacture shades and the like of such material as Will be suitable for and harmonizing with any particular color scheme or any particular period or type of furnishing employed.
